I attended my first Chennai Java Summit last weekend. The one-day conference had two parallel tracks. The conference was organized as part of AIOUG (All India Oracle User Group) and so there was a parallel track covering Oracle technologies as well. Nagaraj Paduvare from Oracle talked about what User Groups. The title of the presentation "User Groups - Are you a member yet ?" clearly conveyed the urge for the community to join the local User Groups - be it Java . Oracle's vision is to promote a world-class user group community where community and customers realize outstanding value from participation and experience constant and healthy dialogue with one another and Oracle at all levels. There are 870+ independent Oracle user groups related by interests and location. You can find all the information about them at iouc.org.
I gave two presentations and the slides are available.
There were about 40+ attendees in this talk. Some of the audience were not even aware of Java EE 6 so I started the talk with a NetBeans-driven introduction to the platform. A more comprehensive video of Java EE 6 tooling with NetBeans is available at screencast #36. The screencast #37 covers the same with Eclipse. And then I explained how Java EE 7 platform is embracing cloud by providing support for dynamic service provisioning, metrics-driven elasticity, and multi-tenancy. Its important to remember that Java EE 7 will offer lot more than cloud as several specifications such as Java Message Service 2.0, Java API for RESTful Web Service 2.0, and Expression Language 3.0. Several other specifications are getting a minor update as well. You can get all the latest updates at javaee-spec.java.net.
The demonstration of taking a Java EE 6 application and deploying it to GlassFish 4 showing service provisioning hit the point home. The complete instructions to download and build the sample are available at glassfish.org/javaone2011.
This talk gave a brief overview of REST Architecture, how JAX-RS provides support for RESTful Web services, and a complete overview of the new features coming in JAX-RS 2.0. I also demonstrated how NetBeans wizards make life simple for generating RESTful Web services from JPA Entity classes. The working JAX-RS 2.0 sample codes convey the point that an early implementation is already available. You can get all the latest updates at jax-rs-spec.java.net.
It was certainly good to spend some time with Venkat Subramaniam and Scott Davis.
On a personal side, I enjoyed Dal-Baati-Churma at a Rajasthani restaurant in the hotel. For me, enjoying the local cuisine is definitely one of the joys of staying in India. However the humidity was very high and so that prevented me from running in the morning. In times like this, the Spartacus Workout from Men's Health Magazine has been really helping me recently. If you have not tried this workout, you must!
Here are some pictures captured from the event:
